Title: Piezoelectric transducer self-travelling apparatus
Inventor: TODA KOJI
IPC: B60L13/03
Filed: 1988-12-09
Abstract: PURPOSE:To move a piezoelectric transducer along a rail by a reaction and facilitate its parallel movement and curved movement by a method wherein the surface of the piezoelectric transducer which shows a large vibration displacement to one direction is brought into contact with the rail. CONSTITUTION:A single-phase AC voltage is applied to a piezoelectric transducer 1. A rail 2 is fixed and the piezoelectric transducer 1 is guided by the rail 2 and moved. The piezoelectric transducer 1 is fixed to a sliding frame 4 with its fixing surface 10c. The sliding surface 10d of the piezoelectric transducer 1 is brought into contact with the bottom of the trench 21 of the rail 2 and the piezoelectric transducer 1 is supported by the bottom and travels freely along the longitudinal direction of the rail 2. The sliding frame 4 slides while the lower ends of both its side wings are brought into contact with the outer side walls of the rail 2 so as to prevent the piezoelectric transducer 1 from turning around its axis in the trench 21. An article can be put on the top surface of the sliding frame 4 and the sliding frame 4 or the piezoelectric transducer 1 can be used as an actuator.

IPC: G03G9/09
Filed: 1989-11-30
Abstract: PURPOSE:To restrain change of chargeability characteristics and to obtain an image high in density without causing toner scattering and image fog by specifying the range of conductivity of the developing toner comprising a binder resin, a carbon black and a carbon black dispersion stabilizer both contained in the binder. CONSTITUTION:The spherical electrostatic charge developing toner comprises the binder resin and the carbon black and the carbon black dispersion stabilizer contained in the binder and it has a conductivity of 5X10<-9> - 5X10<-11>S/cm. When it is set in this range, a large amount of charge triboelectrified because of good fluidity is properly moderated and stable chargeability characteristics is obtained. Since the carbon black has hydroxyl and carboxylic groups and is deteriorated in compatibility with a monomer for constituting the lipophilic binder resin, and in order to allow the carbon black to stably exist in the monomer, the monomer having the carbon black immersed is prepolymerized in advance to form a grafted carbon black, thus permitting the obtained toner to be superior in chargeability characteristics and a high-quality image to be obtained without scattering of the toner and image fog.

Abstract: PURPOSE:To prevent an electrothermal transfer recording film from staggering, enable smooth feeding and contrive stable recording, by providing a plurality of protrusions on the circumference at both ends of the surface of a cylindrical return circuit electrode, the spacing between the both ends being smaller than the width of the recording film. CONSTITUTION:A central part of a return circuit electrode A is provided as a cylinder having a uniform surface, and rings 21 are provided at both ends spaced from each other by a distance smaller than the width of an electrothermal transfer recording film. The outside diameter of the rings 21 is designed to be slightly greater than the outside diameter of spacers 20, and a plurality of protrusions 24 are provided on the circumference of each of the rings 21 at regular intervals. When a feeding force for the recording film is supplied between the electrode A and a pinch roller, the protrusions 24 provided on the electrode A press against the pinch roller, having an elastic surface, while biting the film therebetween. As a result, a sufficient resistance is generated against forces perpendicular to the feeding direction of the recording film, whereby the film is prevented from staggering, and a stabler tension can be contrived through the stabilizer effect.
